Abstract (en)

[origin: EP0985446A2] A continuous stirred tank reactor is paired with a bubble column reactor to enhance conversion in a continuous process, e.g. hydrogenation, wherein a gaseous reactant is mixed with a liquid. The continuous stirred reactor is fitted with a specialized impeller system to circulate the liquid and enhance contact of the liquid with reactant gas carried over from the bubble column. <IMAGE>
